Not much is clear about the Marksman. They apparently use 'crossbows' which are a slow, annoying weapon that block your face when you hold them. Lol@that. Their 4th job skills aren't very intriguing, which is most likely why I always wonder what exactly a Marksman is when I see one walking around HHG1. Sometimes I wonder just -why- they're walking around HHG1, but then it hit me- they're just as nooby as the level 8 magicians. FatalEyes is a good example of this breed. (Marksmanicus Noobicus)
Used in xxxtentacion’s song “Skin” there is no exact meaning but a marksman is someone who is very skilled at hitting a target, and as most people will know X got his heartbroken bad. To give a solid answer to what a heart marksman is it is Someone who is skilled at getting there heartbroken🤷🏾 ♂️
